VALVE-GRINDEB..

Specification of Letters latent.

Patented rl pr. 6. fiil.

T0 all whom it may concern I Be it known that I, JAMES W. ViLsoN, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Gklahoma, have invented certain new and useful Improvements in Valve-Grinders, of which the following is a specification, refer'- ence being had to the accompanying draw ings.

rhis invention relates to new and useful improvements in valve grinders and more particularly to a multiple valve grinder. the main object of the present invention being the provision of a valve grinder consisting of a plurality of valve actuating members and means for imparting simultaneous rotary movement to the same.

Another object of the present invention is the provision of a device of the above charaeter which will possess advantages in points of etliciency and durability, is inexpensiv, to manufacture and, at the same time is simle in construction and operation.

`With the above and other objects in view, the invention consists in the novel features of construction. combination and arrange ment of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

ln the accompanying drawings forming a part of this application. Figure 1 is a top plan view of a valve grinder constructed in accordance with my invention. Fig. 2 is a front elevation; and Fig. 3 is a transverse sectional view.

Referring more )articularl 1 to the drawings, the numeral 1 inflicat-es two spaced.

standards connected by means of a longitudinal member 2. said longitudinal member being suitably braced adjacent its ends by means of the anguhr brace pieces 23. Extending transversely tl'rrough the ends Of tle cross pieces 4 of the supporting in' uibers l. are pivot pins extend through the transverse supporting beams 6 of the movable, frame which supports the operating mechanism. From this it will be Vapparent that. the frame which supports the operating mechanism may be readily raisedand lowered and. when lowered will rest upon the longitudinal member 9.. Supported upon the cross beams 6, are the spaced longitudinal beams 7, said 5, the inner ends of which beams being integrally connected by means of the top pieces or blocks S.

Mounted upon the upper faces of the beams 7 at the medial portions thereof, are the bearings 9 in which is 1r ounted the shaft 10 and mounted upon this shaft is a pulley 11. connected by means of a belt 12 to a second pulley 13 disposed between the beams 7 and arranged beneath one of the blocks t3. rlhis pulley 13 is mounted upon a transverse shaft 1d which is mounted within suitable bearings formed in the beams 7 and one end thereof projects bevond the outer side wall of one of the beams and mounted thereon is a second pulley 15 to which is eccentrically connected a pitman 16. the purpose of which will be hereinafter more fully set forth. ln order to impart a reciprocating movement to the pitman 1G. l provide a crank arm 17 which is secured to the outer end of the shaft 10 and provided with a handle 18, whereby the shaft l0 may be readily rotated when it is desired to impart reciprocating movement to the pitman 16.

Secured to the outer face of one of the beams T. are the spaced guides 19 and movable therein if, a block Q0, the outer edge of which is connected to a reciprocatingy rack bar Q1, while one end thereof is connected to the pitinan 1G so that as the pitman 16 is reciprocatcd. the block Q0 and bar 21 will be actuated simultaneously. This rack bar Q1 slidably mounted within suitable guide openings 22 formed within the end beams 6 and the teeth which are formed upon the outer edge thereof are adapted to Inesh with the gears 23 carried bv the upper ends of the rotating shafts 24e. The shafts 2-1 are rotatablv mounted within suitable blocks Q5 which are adjustably mounted upon a guide plate 2G and the shafts themselvesvare moi able within a slot 27 formed within the plate Q6 so that the blocks 25 may be readilv adjusted longitudinally upon the plate 26, accoi-ding to the character of the engine upon which the device is to be used. Mounted upon the shafts 24. are the coil springs 28 which are disposed between the transverse pins 29 and the blocks Q5. whereby to securely retain the. gears 2B down against the upper face of the blocks so thatI it will` at all times, remain in engagement with the teeth Of the rack bar 21.

The blocks 25 are adjusted longitudinally upon the plate 2G and are securely held in position by means of set screws 30 which are well known type and which will be rotated simultaneously with the reciprocation of the bar 21.

It will be apparent that in arranging this device in position to be used, the frame which supports the operating mechanism is raised and the supporting members 1 placed at each end of the engine and, after the supporting frame has been placed in position, the frame which supports the operating mechanism will be lowered so that the members 21 will be in a position to engage with the valves of the engine. After these have been placed in position, the cra'nk 17 is actuated to rotate the shafts 10 and 14 which, in turn, will impart reciprocating movement to the pitman 16 and the rack bar 21. From this it will be -apparent that all of the valves of the engine may be simultaneously ground upon operation.

It will further be apparent that the blocks 25 may be readily adjusted longitudinally upon the plate 26, so as to adapt the device to different kinds of engines.

It will also be apparent that the device is extremely simple in construction and can be manufacturedv and placed upon the market at a comparatively low cost.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice, without sacrificing any of the novel features or departing from the scope of the invention, as defined by the -appended claims.

Having thus described this invention, what l desire to claim and secure by Letters Patent, is

l. A valve grinder including spaced standards, a longitudinal member connecting said standards, a movable frame hingedly connected to said standards and mounted upon the longitudinal supporting member, a plurality of valve engaging elements, and means for simultaneously actuating said ele* ments.

2. A device of the class described including spaced standards, a longitudinal member connecting said spaced standards,a movable frame hingcdly connected to the standards and adapted to be supported by the longitudinal able blocks carried by said. frame; vertically disposed shafts mounted within said blocks, gear telhxformed upon the ,upper ends of .engaging elements carried member, a plurality of adjust 'guide plate, and means supported by the spaced beams and having connection with said shafts to simultaneously rotate the same.

4. A valve grinder including a movable frame, means for supporting said frame,A a. plurality of vertically disposed shafts adjustably mounted upon said frame, gears carried by the upper ends of said shafts, valve engaging elements carried by the lower ends thereof, a reciprocating rack bar adapted to engage the gears on the shafts, a transverse shaft carried by the'movable frame, a pulley'carried by the shaft, a pitman having one end eccentrically connected to the pulley and its other end connected to the rack bar, and means for imparting rotary movement to the transverse shaft whereby to reciprocate the rack bar and simultaneously rotate the vertical shafts, as and for the purpose set forth.
